You can use a Preventic collar, a Seresto collar, or a topical medication such as Frontline or K9 Advantix along with Comfortis for tick coverage. Or, if you prefer to stick with oral medications, you can switch from Comfortis to Nexgard or Bravecto - both of these cover both fleas and ticks, and are also very effective.

    The most effective options currently available for flea/tick control in dogs are oral medications, including Nexgard, Bravecto, and Trifexis/Comfortis. These are prescription medications, so you would need to get them from your vet. If you need over-the-counter options, K9 Advantix and Seresto collars are both reasonably good options that work well for many dogs.
